I have an Audi A4 2.5 V6 TDI. starts lovely when cold but when warm it doesn't start so easy. So far I've changed the cranking sensor, Glow plugs & ECT sensor . . . Any suggestions?

Can be injectors leaking when parts is warm and expanded or temp sender not sending correct signals to ecu,so get injectors tested and replace temp sender.hope u succeed.

Try turning key to on position for 15-20 seconds before attempting to start that should give the glow plugs enough time to warm up there for making it easier to start
My Vauxhall (Opel) Zafira 2004 1.8 liter 16V Petrol Auto
had COLD START problem; cold engine does not start no
matter what! I have changed the following parts, one after
another:
1. New Coil pack
2. New Spark plugs
3. New Battery
4. New Mass Air flow oxygen meter
5. Air filter
6. Oil filter
7. Engine oil
8. Fuel filter
9. Premium Petrol
10. Engine coolent water sensor
Still the same problem. Then changed 'Crank sensor'. And
now the car starts fine without any issue!!

if it starts OK when warm , but not when cold , I would say it is the temperature sensor, sometimes on the intake manifold, engine block, or even the radiator, but don't confuse it with the fan sensor on the rad.
Locate your crank sensor and make sure the electrical connector pins and sockets are clean and dry and that wiring is in good order. Could be an easy and cheap fix
There is a relay which will make a `clunk` noise under the bonnet. It can be heard a few seconds after the glow plug light on your dashboard goes out. I would suggest that this is the problem. You may have to buy a new one. Very easy to do. Quite cheap as well.
